Future biofuel development direction: let cars eat junk

Competing with food, and food fight, not the intention of developing bio-fuels. Non-food raw materials, energy used to do, let the car eat junk, this is the future of the development of biofuels.
People began to realize that car is a much-needed drink problem, because oil is not renewable energy, may disappear after a few years.
  
Oil as a vehicle for food, there is no doubt that was not enough, while on the road but can not stop the car running. Thus, the wisdom of mankind on their own to develop a new energy, which is both green and resource-rich biofuels.
Pressing the oil crisis of a dead man, the emergence of bio-fuels, and finally to human beings to find a "savior." Through biological resources biological production of these bio-ethanol and biodiesel fuels, the biggest advantage is the source of raw materials to the broad and easy. For example, bioethanol it, through the fermentation of plant starch or sugar can be distilled, and bio-diesel is vegetable oil and alcohol through the (usually methanol) obtained by esterification. Corn, soybeans, wheat and peanut and other food raw materials and straw, sweet sorghum, cassava, sweet potato, sugar cane, sugar beet, silver grass, switchgrass and other non-grain raw materials, can be bio-fuel raw materials. Thus, starting from the 70s of last century, biofuels have become the new darling of energy. Many countries as the use of renewable energy development an important direction, make great efforts to develop. Today, bio-ethanol production from food crops in the way of commercialization in the world.
